Tr) (til whom it may concern.-

Be it known that we, JOHN C. FIDDYMENT, a resident of Brinkley, Monroecounty, State of Arkansas, and JOHN J MCNALLY, a resident of Norfolk, inthe county of Norfolk and State of Virginia, citizens of the UnitedStates, have invented a certain new and useful Press, of which thefollowing is a s ecification, reference being hadtherein to t e accomanying drawin s.

v T 's invention re ates to resses for the and extraction of oil orliquid from vegetab e seeds, such as cotton-seed, castorbeans, nuts ofvarious kinds, fish, brewers and packinghouse products, and any materialcontaimng liquid.

One object of the present invention is to provide a press which will actuniformly on the material as it passes through the machine and at thesame time avoid any tendency of the mass of material to rotate withinthe press-chamber as it is advanced toward the discharge end of thesame. With presses of the ordinary construction there is a constanttendency on the'part of the material to rotate with the expresslng-screwand also to become wadded or congested in the press-chamber on accountof greater pressure bein exerted on the materia at one point, and t soften results'in a severe injury to the ress or the breakage of someportion thereof.

The resent invention overcomes the difiiculty a ove referred to by theuse of a screw of peculiar form and construction whereby the material iscutup or divided at one or more places in its passa e through themachine and also advanced or fed along uniformly, and thus' preventedfrom being compacted to too great an extent at any point within thepress-chamber. Special means are also provided for preventing thematerial from rotating durin the pressing action, and said means are sore ated to the feedin means and the means for cutting up or dividing thematerial that said material will readily adjust itself to the severalelements referred to and the compression will be equalized.

A further object of the invention is to provide means for regulating thefinal pressure iven to the mass as it is being dischar ed om the machineand also means for holding the mass in drainage just prior to its finaldischarge.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination, and arrangement of parts, ashereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection through a press embodying the present invention. Fi 2 is ahorizontal longitudinal section throug the same. Fig. 3 is a verticalcross-section through the press. Fig. 4 is an enlarged detailcross-section through several of the longidinal slats or bars. Fig. 5 isa side elevation of the feeder. Fi 6 is a plan view of one of the slatsor bars Sooking toward the inner grooved face thereof. Fig. 7 is aview-in elevation of the feed looking toward one end of the drum withthe adjacent side of the casing removed. Fig. 8 is a vertical sectionalview of the feeder. Fig. 9 is an end view of a portion of the feedermechanism.

Like reference-numerals designate corresponding parts in all the figuresof the drawings.

The press contemplated in this invention comprises essentially, afeed-screw 1, with a special form of flight or thread and mounted withina casing 2, preferably of cylindrical shape, said casing being firmlysupported by a suitable framework and the screw 1 being journaled inbearings connected with and forming 1parts of such framework. A simpleform 0 ame comprises a series of bearing standards or edestals 3, 4, and5, which are connected by longitudinal beams 6, the journal portions ofthe feed-screw shaft being received in the said bearing-standards andthe cylindrical casing being mounted upon and secured to thelongitudinal beams 6, as clearly shown in the drawings. The feed-screwis mounted to rotate within the casing and embodies a tapering body 7,which gradually increases in size from the receiving end of theress-chamber toward the discharge or de very end thereof, a graduallytapering and contracting annular space being .thus left beculiarconstruction and arrangement, the

threads bein alternately large and small. The smaller tlireads (shown at8) project only a portion of the way from the body 7 toward the innerwall of the press-chamber, while the larger threads 9 project to withina very short distance of the wall of the press-chamber. The smallerthreads, which serve to advance the material along the press-chamber,alternate with the larger threads, which serve to out up, divide, orseparate the material during its progress through the machine and alsoadvance the material at the same time. In this way the pressure on themass within the press-chamber is distributed and equalized and unduepressure, wadding, and congestion at one or more points obviated, thematerial being divided as it is advanced or fed along. As illustrated,about two small threads intervene between each pair of large threads;but it is to be understood that the number of threads of each charactermay be increased or diminished at will, as may also the entire number ofthreads on the feedscrew, thus providing for any desired pitch of threadand consequent speed of feed of the material through the press. Theshaft 1 of the screw will be suitably shouldered adjacent to itsbearings to prevent end thrust.

The discharge end of the body 7 is also preferably rounded ofl orchamfered, as shown at 10, to facilitate the delivery of the compressedmaterial from the press.

The cylinder or casing 2 is composed of a circular series oflongitudinal slats or bars 11. These extend the entire length of thepresschamber, and their inner faces form the 'inner wall of thepress-chamber. The side faces of the slats abut directly against each'other for approximately one-half their extent or area, while theremainder of their side faces are beveled to form flaring oroutwardlyexpanding exits for the juice or liquid as it escapes fromthe-press-chambera The abutting faces of the slats are transverselygrooved at o posite points to form drain-ports 12, whic communicate attheir outer ends with the flaring exits 13 and at their inner ends openinto strainerassages 14, which extend lengthwise of the s ate and arelocated adjacent to the inner wall of the press-chamber, as best shownin Fig.1, narrow spaces or slits 15 being left at the inner corners ofthe slats to receive the liquid and admit the same to the strainer-passaes, the latter being adapted toreceive strips 0 absorbent or filteringmaterial, which allow the liquid to pass, but arrest solids. The slatsor bars 11 are all secured to rings or hoops 16, which encircle theslats, as shown in Figs. 1, 2, and 3. These bands or hoops are referablymade in semicircular sections, as est shown in Fig. 3, and said sectionsare by reference hinged together at one side of t e press, as shown at17, and connected at the opposite side by bolts 18 or their equivalentin order that the upper portion of the press-chamber may be opened upand thrown back to give access to the interior thereof, the lower halfof the press chamber thus formed being secured rigidly to the frameworkof the machine.

In order to prevent rotation of the material as it is fed along throughthe press-chamber, use is made of one or more baffles 19, one of suchbaflies being shown in Figs. 2 and 3, in which it is illustrated asconsisting of a metal strip or plate inserted between the meetingportions of the press-chamber sections at one side of the machine andheld by the bolts 18.

-The.operative portion of the baflies consists of one or more insetprojections or extensions 20 of proper extent to lie between the sets oflonger threads 9, where said projecting portions of the baffles enterand engage the material and offer a ositive means for reventing theturning o the mass within t e presschamber and also insure the properfeeding of the -material through the press and its delivery therefrom.

At the discharge end of the press-chamher is arranged a resistance orpressure plate 21, circular in shape and provided with anoutwardly-contracting discharge-orifice 22, through which the compressedmaterial passes in being delivered from the press. Theoutwardly-projecting flange of said plate is provided with openings toreceive bolts 23, which also project from the end of the presschamberand render the resistance-plate adjustable towardand away from thedischarge end of the press-chamber for giving greater or lesscompression to the material as it escapes from the press. The bolts 23pass throu h the plate 21 and receive nuts outside of said plate. Byturning said nuts the position of the resistancelate 21 may be varied,and by removing sai nuts the plate 21 may be detached, after which thehinged section of the press-chamber may be thrown open to give access tothe interior of the chamber.

In Fig. 2 it will be observed that the rear end portion of the body 7 ofthe feed-screw is made cylindrical instead of tapering, as in Fig. 1.This is found desirable in some instances in order to hold the meal orother material in drainage for a part of the time just prior to deliveryfrom the machine. It Wlll also be noted by reference to Fig. 6 that thedrain-ports decrease in size as the rear ends of the slats areapproached, but increase in number or are arranged closer together, sucharrangement having been found of advantage in use to more effectivelyadmit of the esca e of the liquid.

T e feeder consists of outer and inner members 24 and 25, respectively,as best shown in Fig. 8, the outer member being in the form of a drummade up of segment-bars 25, betweenwhich are left inwardly-fiarin spaces26 to permit the sliding movement 0 oscillate as they move outward andinward" relatively to the outer drum. The members '24 and 25 are bothmounted in -a casing 29, leading into the press-chamber, and alsoprovided with a segmental offset 30, in which the projecting portions ofthe blades or wings- 27 move in a downward direction for forcing thematerial in a corresponding direction into the press-chamber. The drum24 is provided with a hollow shaft 31, mounted in bearing-standards 32,while the shaft of the inner member passes through the drum and isjournaled in bearings 33 outside of and beyond the bearings 32. The twoaxes of rotation are eccentric to each other, as shown in Figs. 7, 8,and 9, and in order to cause both members to rotate together a couplingdevice or key 34 is secured to one of the members, as shown at 35, andhas a sliding engagement and interlocked connection with the othermember by passmg the same through a loop or keeper 36, as shown in Fig.9. Under the arrangement described the two rotary members of the feeder,while eccentrically arranged, are driven together at the same speed,causing the outer ends of the blades or wings to be alternatelyprojected and withdrawn in the manner illustrated in Fig. 8.
